The dpa 300B is an unique Highend Hifi poweramplifier. It is not Single Ended or Push Pull, but uses a differential (balanced done correctly) amplifier circuit topology to provide the best sonic attributes of both, without their weaknesses.
Allen Wright's excellent DPA 300B amplifiers with the MaxxHorn Immersions share the spotlight in a mini review by Roger S. Gordon, Positive Feedback, Issue 21.
"The combination of the Vacuum State dpa300Bs with the MaxxHorns was a marriage made in heaven. All the problems that I had heard on my initial listen disappeared. With the dpa300Bs, the sound was coherent, detailed, dynamic. This was easily the best sound that I had heard at the show. After half an hour of listening I had to leave in order to meet some friends for dinner. I had just left the room and was saying good bye to Allen out in the hall where he had been conversing with one of the Rhino people when I suddenly heard Bela Fleck's Flight of the Cosmic Hippo coming from the room. I know and love this bass guitar piece and use it as my test track when demoing subwoofers. Back into the room I went. What I heard was the best sounding Cosmic Hippo I have ever heard and I have heard it on quite a few systems including my own."
Thank you Allen Wright, Vacuum State Electronics for your very special efforts to bring your amplifiers to our room for a very special audition.
